T 0 all whom it may concern:

Be it known that I, Faannmc H. DAY, a citizen of the United States, anda resident of Hopewell, in the county of Prince George and State ofVirginia, have invented a new and useful Improvement in Car-Door Locksand Seals, of which the following is a specification.

My present invention relates generally to means for securing car doors,and more particularly to im rovements in car door locking devices emdying a seal in connection therewith, and so constructed as tonecessitate the use of a ke for unlocking the door in addition to breaing the seal when it is desired to open the car door, my object beingthe provision of an arrangement whereby to obviate the presentconditions under which members of train crews, for instance, may obtainunwarranted access to a car by simply breaking the seal.

In carrying my invention into use, it is my intention to rovide stationfreight agents alone, with eys necessary to unlock the car door, so thateven should the seal become broken in transit, either due to accident orto intentional breaking for purpose of robbery, the car door will stillresist efforts, byvirtue of its key-controlled locking features, atentrance thereinto.

In its more specific aspect, my invention resides in the features ofconstruction, arrangement and operation to be now described with respectto the accompanying drawings, forming apart of this specification. andwherein:

Figure 1 is 'a fragmentary side elevation including a portion of a carside and its door, equipped with my improvements.

Fig.2 is a horizontal sectional view taken therethrough substantially online 2-2 of Fig. 1. I

Fig. 3 is a vertical section taken therethrough substantially on line 33 of Fig. 1.

Fig. 4 is a similar view taken substantially on line 4-4 of Fig. 1,illustrating the parts in locked position.

side and itsdoor provided with myian- L Fig. 5 is a view similar to Fig.4 illustrating the parts inunlocked position.

Fig. 6 is a detail perspective view of the locks arm removed. 7

Fig. 7 is a detail perspective view of the latch bar removed, and

Fig. 8 is a perspective side viewof a car rovements and illustrating thelatter in ocked position.

Referring now to these figures, and articularly to Figs. 1 and 2, Ipreferably utllize a lock arm 10 having aneye at one end by means ofwhich it is pivotally connected to a car door A, the eye receiving theouter portion, for instance, of a U-bolt 12 secured through'the door, soas to thus permanently hold the arm in horizontally movable relation andadapt the same to shift flatwise a ainst the adjacent outer face of acar side B at one side of the door A.

At the latter portion of the car side B I utilize a lock casinggenerally indicated at 13, mounted within a rectangular cut-out portionof the car side of substantially the shape of the lock casing, thelatter of which has an enlarged rectangular front plate 14 which Ipreferably counter-seat within the outer face of the car side and secureby means of bolts 15 extending through the car side, at the same timelocking both the bolts 15 and bolts 16, the latter serving to connectthe lock casing 13 with its front plate 14, by means of cotter pins orother devices 17 calculated to remove all danger of bodily removal ofthe lock casing.

The front plate 14 has an intermediate rectangular opening 18 and a keyslot 19, the former being positioned to receive the angular keeper 20 ofthe lock arm 10, projecting laterally from the free end of said arm,adjacent to a handle 21 by means of which .the said arm mav be readilygrasped and moved either to the locked position shown in Figs. 1 and 2,or a released position away from the lock casing.

\Vithin the lock casing 13, a latch bar 22 is pivoted at one end at 23,and has a out out portion intermediate its ends forming a beveledsurface 24 for engagement with the angular keeper 20, said latch bar 22normally extending in a substantially horizontal-position as indicatedin dotted lines in Fig. 1, and resting at its free end upon an internalpin 25 with n the lock casing 13. forming a stop, the free end of thesaid latch bar being acted upon by the free end of a spring 26 securedat its opposite end at 27 within the lock casing, to normally hold thesaid free end of the latch bar downwardly against the stop pin 25.

Thus, the latch bar normally extendsin operative position and when theangular from the front plate 14 so as to admit of a bridge wall betweenthe same and the front plate 14, said bridge wall being indicated at 29in Figs. 2, 4 and 5 in partlcular, and being itself spaced from thefront plate 14 in order to normally protect the latch bar against theaction of tools or implementsother than a. key designed particularlylfor elevating the same, and as seen genera y at 30 in Figs. 4 and 5.

At a oint intermediate its ends, the lock arm 10 as an outwardlyprojecting ear 31 provided with large an small openings 32 and 33,respectively, this ear being arranged to extend between verticallyspaced and similarly shaped ears 34 and 35 projectin laterally from thefront plate 14 of'the loc casing, and having similar lar e and smallopenings. A locking pin 36 is a so provided, anchored by means of achain 37 to a portion of the car side, and movable through the enlargedopenings of the several'ears 31, 34,

and 35 with the lock arm 10 in locked position shown in Figs. 1 and 2,the said pm 36 having a small transverse opening ad acent its free end,which in the operative ositionthereof shown in Fi 3, extends beow thelowermost ear 35 of t e series,'for the rece tion of a portion of'thewire 38 to which 1; a seal 39 is applied, said wire being extendedthrough the smaller openings of the several alined ears including thesmall opening 33 of the ear 31.

In this wa the door is not onl locked by virtueof the engagement of theetch bar 22 with the lock arm 10, but relative shifting movement of thelock arm is revented b means of the locking pin 36 an the latter isinturn sealed agamst removal by the exten sion of a portion of the wire 38of the seal 39 therethrough.

It is therefore obvious that by providing only the freight agents atthe" various stations with keys 30 to the lock, it will be impossible toopen the car door in tangent, and great losses by theft of train crews,

tramps, and others, will be avoided, and blame for losses more readilydetermined and justly placed. I

I claim:

1. In a device of the character described, a lock arm ivoted at one endand ro vided with a handle and a laterally pro ecting keeper adjacentits opposite end, a lock casing havin its front p ate provided with anopening r the reception of said keeper, 9. latch'bar within the saidcasing and p1voted at one end, said latch bar having an intermediatebeveled portion opposite the openin of its front plateand for engagementwith the said keeper of the lock arm, means within the casing tonormally hold the said latch bar in operative position and including aspring engaging one side of the latch bar to emit the same to yield inone direction,

lock casing having its front plate provided with a key slot, and abridge wall within the lock casing, spaced from the front plate thereofand disposed between the front plate and the latch bar, adjacent to thesaid key slot, for the purpose described.

2. In a car door lock, the combination of a stationary lock casingincluding a keyactuated latch bar and means to normally hold said latchbar in operative position including a spring engaging one side thereofto-permit the same to yield'in one direction, and a horizontallyswinging lock arm pivotally mounted at one end and having its oppositeend provided with an angularly disposed handle, and a laterallyprojecting keeper, the latter of which is movable into 3. A car doorlock including a lock casing having internal key-actuated lockingmemthrough certain of the openings of the said earsand having anaperture adjacent its free end, and a sealing member for extensionthrough the other apertures of the said ears and through the aperture ofthe said lock FREDERIC HENRY DAY.
